Randomized Controlled Trial Comparative Study
[Postoperative metabolic acidosis: use of three different fluid therapy models].
Intraoperative fluid administration is considered an important factor in the management of metabolic acidosis following surgical procedures. The aim of this study was to compare three types of intraoperative infusional models in order to evaluate their effect on acid-base changes in the immediate postoperative period as calculated by both the Henderson-Hasselbach equation and the Stewart approach. Forty-seven patients undergoing left hemicolectomy were enrolled in the study and assigned randomly to receiving 0.9% saline alone (Group A, n=16), lactated Ringer's solution alone (Group B, n=16) or 0.9% saline and Ringer's solution, 1:1 ratio (Group C, n=15). ⋯ The results showed a metabolic acidosis status in Group A patients, whereas Group B exhibited metabolic alkalosis only by means of the Stewart method. No difference was found in Group C between the time points t0 and t1 when using either the Henderson-Hasselbach equation or using the Stewart model. We conclude that saline solution in association with Ringer's solution (1:1 ratio) appears to be the most suitable form of intraoperative fluid management in order to guarantee a stable acid-base balance in selected surgical patients during the immediate postoperative period.

Traumatic lesions involving the rectum, perineum and anus are infrequent but difficult to treat, requiring experience with trauma and colo-proctological surgery. The aim of the treatment is to repair the lesions and to minimise the early complications which are the main cause of failure and of late complications and disability. The most complicated lesions present problems concerning either the surgical strategy or the surgical timing, both of which are essential for a successful outcome. ⋯ Only two cases (28.6%) of early complications and one case (14.3%) of persistent minimal sphincter dysfunction occurred. On the basis of these good results, the clinical experience and the literature, the Authors suggest that these perineo-ano-rectal lesions, though often complex, may often be cured by early surgery, confining colostomy only to particular cases. In addition to experience with trauma and the timing of colo-proctological surgery, a knowledge of all the available surgical options is mandatory to achieve the best results.

Traumatic hernia of the abdominal wall is a rare type of hernia. A high-energy, localised impact causes the disruption of the abdominal wall musculature without penetrating the skin. ⋯ A high level of clinical suspicion is required for diagnosis because of the high rate of associated injuries. The authors report a case of handlebar hernia managed successfully by surgical repair.

Review Case Reports
Splenic rupture after colonoscopy. A case report and review of the literature.
Rupture of the spleen after colonoscopy is a rare but dangerous complication; up to now only a few cases have been reported in the literature. This complication is more frequent in patients who have previously undergone abdominal surgery and after operative colonoscopies. ⋯ Laboratory exams showed anaemia; the patient also developed hypotension and tachycardia; a CT scan revealed a splenic laceration with haemoperitoneum. A laparotomic splenectomy was successfully carried out.

We report a case of recurrent abdominal pain due to intermittent caecal volvulus arising in a patient with mesenterium commune. Colonic enema, abdominal CT scan and virtual colonography with three-dimensional colonic reconstruction were useful for detecting this rare abnormal intestinal fixation. Although right hemicolectomy was indicated, we performed a wide colonic resection from the terminal ileum to the distal sigmoid because the patient's short mesentery made it impossible to perform an ileum-transverse anastomosis. At six months follow-up, the patient was in good health and free of abdominal symptoms.
